I absolutely enjoyed my stay at Susan's place. It was exactly as described, had all the amenities you could expect from a fully furnished apartment, check-in was great and Susan and her team were very responsive.
Susan's apartment is located in a nice and peaceful neighborhood. There are two MRT stations within walking distance and there's also an Airport Rail Link station to take you to and back from the Suvarnabhumi airport.
There's also a 7-Eleven right at the front of the building stocked with all the essentials you'd generally need on a trip.
I'm definitely staying at Susan's place the next time I'm in Bangkok!
